I had a scary first experience with the Flex Builder 2 (2.0.1) Trial on the Mac, after having commenced a project using the Beta…
Before installing, I was aware of the following bullet in the release notes…
Opening old Flex projects – The Flex Builder 2.0.1 update cannot open projects that were created with pre-release versions of Flex Builder 2. Flex Builder 2 beta-level projects must be recreated in Flex Builder 2.0.1.
So I zipped a back-up copy of my project files.
On installing and launching 2.0.1, I was suprised that my existing projects seemed to open ok. But ‘cleaning’ the project had the effect of removing the html files. Additionally seemingly spurious errors were generated on compile. The first being 1023: Incompatible override.
I keep my project files on a seperate disc away from the default location. So I deleted the folder and restored just my source files from a zip and recreated the project in builder 2.0.1 – still no joy. In-fact even creating a new application project with only the default stub resulted in errors reported at lines which didn’t exist. (Similar to these reported issues on Flexcoders).
I found the issue to be primarily that the 2.0.1 Builder looks for the same workspace files as the Beta – and they aren’t compatible. The solution…
Rename the existing “Flex Builder 2” folder to “Flex Builder 2 Beta” to accurately reflect the builder that created it. (Just to ensure you can revert to using the Beta if you need to – which I thought would be a likely prospect if my experiment failed) On the Mac:
/Users/username/Documents/Flex Builder 2
becomes
/Users/username/Documents/Flex Builder 2 Beta
(Note: for Flex Builder 2 Beta to pick up it’s workspace again, you need to choose “File>Switch workspace…” from the menu. Not that you’ll want to go back to the beta, once you have 2.0.1 running properly.)
Then when launching the 2.0.1 version, the “Flex Builder 2” folder will be re-created but this time containing a 2.0.1 compatible workspace. You can then start creating projects, porting your old source files as you see fit.
All the spurious errors are now cleared, and proper html files created. So far looking good with improved performance over the beta!
